FREDERICK SUTER, OF BROOKLYN, NEW' YORK.

MACHINE FOR TURNING- THE LEAVES OF BOOKS.

Specification of Letters Patent No. 18,935, dated December 22, 1857.

To all 'whom 'it may concam:

Be it known that I, FREDERICK SUrnn,

of the city of Brooklyn, in the county of Kings, in the State of NewYork, have invented a new and Improved Machine for Turning the Leaves ofMusic-Books; and I hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawingsand to the letters of reference marked thereon.

Figure I is a vertical section and Fig. II a plan of the apparatus withthe top plate removed, the other gures represent de- ZLIlS, 85C.

The apparatus consists of a box A containing the mechanisms, to which astandard B is attached to support the music book. On the top of thisstandard a sliding piece, C, is fixed, capable of being regulated tosuit the height of the music, and provided y with a spring catch, n, tohold the upper end of the music book. The lower end is held fast by* thepin, 0, fast to the slide, m, and acted upon by a spring. This slide, m,is pulled back, while the book is placed against the stand by means ofthe projection, fw, passing through the top plate, D.

In the bottom of the box a rack, R, is situated, acted upon by the bellcrank, E, which latter is operated in one direction by the rod, F, andbrought back again by the action of the spring, G.

H, is a lever, turning on its axis and provided with a pinion, a,working in the rack, R, and by which said lever is turned around, takingwith it one of the leaves of music as will be hereafter described.

2, is a small pin fast to the rack, R, and connected with a lever, (l,which latter acts upon the arm, g, so as to communicate a motion to thelingers, 3, and, 4t, around their axis, 5. The lingers, 3, and, t, areattached to a tube, 8, capable of sliding on the axis, 5, and acted uponby the small spring, 6. A small rod, g, is connected with this tube, 8,projecting through the outside of the box A, so as to pull this tubetogether with its fingers back when required.

Through the finger 4 the front leaf of music, on the right hand side, isheld fast until the same is taken away by the lever H, during whichoperation the finger 3 passes between the second and third leaf, toprepare this second leaf to be in a position to be taken hold of by themechanisms on the lever H when required to be turned,

or after the first leaf has been turned around, to be ready to be turnedaround by said lever H as soon as desired.

K, is a segment attached to the bottom of the box A.

The lever H, of which one side is shown in Fig. I, and the opposite sidein Fig. III has two arms M and N attached turning independently of eachother on a pin, j'. On the end of the arm N a small nose or projection,s, is made, fitting into a lever, 2),

turning on pins fast to the lever H. A spring, l2, acts against this armN so as to push the same upward, as soon as relieved by the lever, 0. Onthe end of the arm M a small roller, 1, is provided through which saidarm is raised up, while passing from the left to the right, over theinclined surface of the segment K. A hook, 7c, acted upon by a spring,18, and attached to the lever H catches on the underside of aprojection, o, provided on this arm M (Fig. III and keeps this arm inthis raised up position while returning from the right to the left.

fc, is a small lever attached to the arm, M, capable of a slight motion,the upper end of this lever, a, is pointed, while the lower end issituated behind the lever, j), and acts upon the same, when moved, so asto throw said lever, j), clear of the nose, s, to allow the arm N to bemoved upward.

c, is a projection attached to the arm, N, and iitting into a recess onthe arm, M, to prevent the arm N from being pushed up too high.

A spring, 14, acts upon the arm M to pull the same, as well as the arm Ndown again as soon as the hook, 7c, is pushed free from the projection,e, of the arm M. Behind the hook, 7c, a small lever .e is situatedattached likewise to the arm M, and capable of a slide motion around itscenters, for the purpose of pushing the hook, 7e, away from theprojection, o, when required.

When the lever, H, is b v the action of the spring, G, moved from theleftto the right, and passes over the inclined surface of the segment,K, the arm, M, is lifted up, as before described, and held in thisupward position by the hook, 7c. As soon as the lever, ai, touches themusic the lower end of the same is thereby thrown a little out, so as topush the lever, p, clear of the nose or projection, s, on the end of thearm, N

forces said arm N upward, thereby bringing the point, u, on the top ofsaid arm behind the music leaf and thereby locking this leaf between theend of the lever, x, on the arm M and this point, u, on the lever, N. Bypulling on the rod, F, the lever H with its mechanisms, which as abovedescribed holds the music leaf fast is moved round to the left takingwith it the leaf, and consequently turning` the same over. The fingers 3and, 4, are at the same time operated on as above mentioned. As soon asthe lever I-I arrives on the left side the hook, c, comes in contactwith the .back of the box or with the music turned over before, andthereby pushes the hook, 7c, clear of the projection, n, when thespring, 14, acts upon the arm, and pushes the same together with the armN down again so as to bring the top of the lever, and the point, u,below the bottom of the leaf, leaving thereby the same free and at thesame time allowing the lever H to pass back again, ready for the nexttime, without disturbing the leaves already turned.

To prevent the leaves being torn it is advisable to attach to that partof the leaves, which are taken hold of by the mechanismsy of the lever,H, metal plates.

Instead of the above described construction the same may be made asrepresented in Fig. IV, Where the lever H is moved by means of a lever,C, which is operated by the rod, c, attached to the bell crank E. Andthis lever, C, works at the same time a plate, p, to which the segment,K, is attached. By this arrangement the whole movement is easierregulated. The mechanisms of the lever H and other parts not shown here,being the same as above described. The rod F by which the bell crank Eis moved may be carried to any point most convenient to be operated.

IVhat I claim as my invention and desire to secure by Letters Patentis- 1. The arrangement of the lever H with the described mechanisms,operating in the manner specifiedfor the purpose of taking hold of themusic leaf, turning the same over, and afterward letting said leaf looseagain, and dropping down, so as to pass under the same, in the mannersubstantially as described.

2. I claim the fingers 3 and 4f operating in the manner and for thepurpose specified.

FREDERICK SU'IER.
